Solution Overview
Problem
Existing refrigeration devices with heat exchangers require numerous temperature sensors along their length for effective defrosting and monitoring, which is complex, costly, and difficult to implement, especially in prefabricated heat exchangers with fins or ribs.
Innovation Solution
A heat-conducting tube filled with refrigerant, acting as a heat pipe, is inserted at an angle into a recessed groove in the heat exchanger, allowing for efficient temperature detection and monitoring over the entire length with minimal components and easy installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple temperature sensors are provided at different points on the heat exchanger, then temperature monitoring reliability is improved, but device complexity and cost increase
Solution Approach 1:
The patent combines multiple temperature sensing functions into a single heat pipe component. The heat pipe contains refrigerant that circulates through its inclined structure, allowing it to detect temperatures at multiple points along its length simultaneously. This merging of multiple sensing functions into one component reduces device complexity while maintaining monitoring reliability across the entire heat exchanger length
Solution Approach 2:
The heat pipe serves multiple functions: it acts as both a thermal conduction path for refrigerant circulation and a temperature detection means. By making the temperature detection system multi-functional, the patent eliminates the need for separate sensors at multiple locations, thereby reducing the number of components and overall system complexity while ensuring reliable temperature monitoring
2Reliability
If multiple temperature sensors are installed along the heat exchanger length, then complete defrosting control is improved, but installation difficulty increases
Solution Approach 1:
The patent merges multiple temperature detection functions into a single heat pipe that can be installed in one location. The inclined heat pipe allows refrigerant to circulate and detect temperatures along its entire length, providing comprehensive defrosting control data without requiring multiple separate sensor installations at different heat exchanger points
Solution Approach 2:
The patent extracts the temperature detection function from multiple separate sensor locations and consolidates it into a single heat pipe component. This extraction simplifies installation by requiring only one access point on the heat exchanger while still providing temperature information from multiple effective positions along the heat pipe's inclined path
3Measurement precision
If a large number of temperature sensors are used, then temperature detection precision is improved, but cost increases
Solution Approach 1:
The patent combines the temperature detection capability of multiple sensors into a single heat pipe. The heat pipe's inclined structure allows refrigerant to circulate and equilibrate with temperatures at various points along its length, providing precise temperature detection data without requiring multiple separate sensor components
Solution Approach 2:
The heat pipe performs the universal function of temperature detection across multiple locations simultaneously. By using the refrigerant circulation within the heat pipe as a multi-functional detection mechanism, the patent achieves comprehensive temperature monitoring precision while using only one detection component instead of multiple sensors

Function Achieved in This Case
This solution enables effective monitoring and defrosting of refrigeration devices with fewer sensors, reducing installation complexity and cost, while maintaining efficient operation and minimizing defrosting time.
Implementation Method 1
a heat-conducting tube filled with a refrigerant is provided as the temperature detection means
Implementation Method 2
the refrigerant reappears due to circulation inside the heat pipe
Implementation Method 3
the two-phase mixture of refrigerant condenses at the coldest point of the heat pipe
Implementation Method 4
The coldest temperature then automatically goes down together with the cold part of the refrigerant due to the inclined arrangement
